error in caling a method. (java)

Question

in this program I want to show pascals triangle using users' input. but there is an error. what is the error in calling pascaltriangle method? (the error says, multiple markers at this line). How can I fix this? thanks in advance.

import java.util.Scanner;

public class pascal{
    static int userinput=0;
static Scanner myscanner= new Scanner(System.in);

public static void main(String[] args) {
    prln("give pascals' triangles length:");
    int userInput=myscanner.nextInt();
    if(userInput>0){
            pascalstriangle(userinput);
    }
}


    static void pascalstriangle(int a){
        int pascal[][]= new int[a][a];
        for(int c=0;c<a;c++){
            pascal[0][c]=1;
            pascal[c][0]=1;
        }
        for(int row=1;row<a;row++){
            for(int column=1;column<(a-row);column++){
                pascal[row][column]=pascal[row-1][column]+pascal[row][column-1];
            }
        }
        for(int row=1;row<a;row++){
            for(int column=1;column<(a-row);column++){
                pr(pascal[row][column]+"\t");
            }
            prln("\n");
        }

    }




public static void pr(Object cop)   {
    System.out.print(cop);
}
public static void prln(Object c6op)    {
    System.out.println(c6op);
}

}

Here I found some problems in your code.

1. Instead of

    pascal[row][column]=pascal[row-1][column]+pascal[row[column-1]; 

use

pascal[row][column]=pascal[row-1][column]+pascal[row][column-1];

2. check main() method closing braces.
3. check class closing braces.

Not only these. some more problems are there..
